    This operating manual contains important information on the use, maintenance and safety of your Kemppi product. The technical specifications of the equipment can be found at the end of the manual. Please read the manual carefully before using the equipment for the first time. For your own safety and that of your working environment, pay particular attention to the safety instructions in the manual.

  • Page 6: 1.2.2 About Welding

    If using aluminium or stainless steel filler wire, we recommend you change the wire liner to a Kemppi plastic type, which is better suited for the material. Before using the equipment, always make sure it was not damaged during transportation.

    This is particularly important for soft filler wires such as aluminium. It will also improve feed quality and increase the service life of your gun liner. Kempact 251R, 253R, 323R, 181A, 251A, 253A, 323A...

  • Page 15: Setting The Pressure Of The Feed Rolls

    Too much wire feed roll pressure may flatten the filler wire, damage its coating, increase NOTE! friction and result in the filler wire sticking in the welding gun liner or contact tip. Also excessive pressure will result in increased wear to wire drive roll bearings, reducing their life. © Kemppi Oy / 1135...

  • Page 17 For aluminium and stainless steel filler wires, always use Kemppi DL Teflon gun liners. These liners are especially developed by Kemppi and significantly reduce friction losses, so improving welding performance and quality.

  • Page 18: Changing The Feed Rolls

    However, it may be necessary to select alternative feed rolls to suit different filler wire sizes used. So you may occasionally need to replace the feed rolls. Kemppi feed rolls and gun liners are colour-coded in order to make identification easy.
